Our take

Based on the ratings of 25 students, a sample of their written reviews and the syllabus, as the course stood in July 2026. No course pays to be reviewed.

Boris Paskhaver's course teaches backend development through FastAPI, and it is aimed at people who already write Python. Across 25.5 hours and 161 lectures, it starts with clients, servers and routes, then builds a rent-a-room project modeled on home-stay sites like Airbnb. Along the way it covers Pydantic, SQLModel, SQLAlchemy, SQLite, Alembic and uv. Despite the All Levels tag, the requirements ask for intermediate Python and some terminal comfort, so people new to programming should start elsewhere.

Reviewers are almost all positive, and they keep coming back to the teaching. They describe clear, fluid explanations that break backend ideas into small pieces. One reviewer with some backend experience says they still picked up new vocabulary, and another likes the focus on the "why" behind API requests. One reviewer with little backend background says it taught fundamentals, not just FastAPI syntax. The complaints are small. One student wishes for a pytest section and a Docker plus PostgreSQL deployment section, and the section list shows no dedicated testing or deployment block, even though the description mentions testing. There are no quizzes or coding exercises either.

The course is new, published in July 2026, with 25 reviews and 443 students so far, so the 4.8 rating rests on a small group. Authentication is the longest section at about five hours, covering password hashing, JWTs, roles and scopes. For Python developers who want a guided, project-first way into FastAPI, it looks like a strong pick. Plan to find testing and deployment material somewhere else.

Best forPython developers who want to build a real rent-a-room API and learn auth, ORMs and migrations alongside it.
Skip it ifYou want pytest, Docker or PostgreSQL deployment, or you are still learning basic Python.

Pros

  • Reviewers praise clear, fluid explanations that break backend ideas into small pieces
  • Rent-a-room project ties routes, ORM, relationships and Pydantic validation together
  • Authentication section runs about five hours: password hashing, JWTs, roles and scopes
  • Updated in July 2026 and uses current tools like uv, SQLModel and Alembic

Cons

  • One reviewer missed a pytest section and a Docker plus PostgreSQL deployment section
  • No quizzes or coding exercises, so practice is left to the student
  • Only 25 reviews so far, so the 4.8 rating comes from a small sample
Boris has a knack for breaking down backend development into its simplest pieces.

Tagged All Levels, but it expects intermediate Python and terminal skills. Best for developers new to backend.

What you will learn

  • Build and run FastAPI applications with endpoints that accept requests and return responses
  • Use SQLModel and SQLAlchemy to define domain models and map them to database tables
  • Use an object-relational mapper (ORM) to perform CRUD (create, read, update, delete) operations with a database
  • Utilize Pydantic to validate and control the shape of data entering and leaving an API
  • Build an authentication and authorization system from scratch with password hashing, JWTs, roles, and scopes

Who it is for

The instructor says it suits

  • Intermediate Python developers who want to learn backend development from the ground up.
  • Django or Flask developers who want to expand their toolkit with a modern, high-performance API framework.

What you need before you start

  • Intermediate knowledge of Python (control flow, data types, functions/methods, classes, imports, etc)
  • Terminal experience
  • Text editor (we use Visual Studio Code in the course)

Course Description

Welcome to FastAPI Masterclass, a comprehensive introduction to backend development in Python with FastAPI.

FastAPI is a Python framework for building fast, modern server-side applications and APIs. It  has exploded in popularity in the last few years. Today, it has more than 100,000 stars on GitHub and more daily downloads than Django and Flask on PyPi. It powers applications in companies like Netflix, Microsoft, Uber, OpenAI, and Amazon.

One of FastAPI’s greatest strengths is its flexibility. Unlike larger frameworks that impose a specific structure, FastAPI gives developers the freedom to choose how their applications are organized. You can customize the folder structure, database, ORM, authentication system, validation rules, testing strategy, and architecture.

No previous backend development experience is required. This course follows a linear progression, beginning with the fundamentals and gradually advancing to topics such as authorization, authentication, testing, architecture, and more.

Topics covered:

  • Clients and servers

  • Routes and HTTP methods

  • Path parameters

  • Query parameters

  • Debugging with Visual Studio Code

  • Cookies and Headers

  • FastAPI Validator Functions (Path, Query, Cookie, Header, and More)

  • Dependencies (Functions, Classes, and Other Callables) and Dependency Injection (DI)

  • Object-Relational Mappers (ORM)

  • Database Queries

  • Database Migrations

  • Codebase Structure

  • Password hashing

  • JSON Web Tokens (JWTs)

  • Authentication

  • Authorization

  • and more!

In addition to FastAPI, the course covers many helpful libraries and tools from the modern Python ecosystem including:

  • uv

  • Pydantic

  • SQLModel

  • SQLAlchemy

  • SQLite 3

  • Alembic

The first part of the course offers a step-by-step walkthrough of a rent-a-room project inspired by home-stay platforms such as Airbnb. We begin from scratch and gradually incorporate all the critical components of a modern FastAPI application.

After the main project, the course explores common backend topics in dedicated sections. These include database migrations, password hashing, JWT-based authentication, authorization, application architecture, and automated testing.

By the end of FastAPI Masterclass, you will not only understand the syntax and features of FastAPI but also understand the fundamental backend principles that apply across programming languages, libraries, or frameworks.

I'm excited to teach you everything I know about this powerful framework, and I look forward to seeing you in the course!

Instructor Details

Boris Paskhaver

Hi there, it's nice to meet you! I'm a New York City-based software engineer, author, and consultant who's been teaching on Udemy since 2016.

Like many of my peers, I did not follow a conventional approach to my current role as a web developer. After graduating from New York University in 2013 with a degree in Business Economics and Marketing, I worked as a business analyst, systems administrator, and data analyst for a variety of companies including a digital marketing agency, a financial services firm, and an international tech powerhouse. At one of those roles, I was fortunate enough to be challenged to build several projects with Python and JavaScript. 

There was no formal computer science education for me; I discovered coding entirely by accident. A small work interest quickly blossomed into a passionate weekend hobby. Eventually, I left my former role to complete App Academy, a rigorous full-stack web development bootcamp in NYC. The rest is history.

Good introduction into FastAPI and some of the backend concepts. Highly recommend.

By Rezan Mohammad on 8/31/2026

No doubt it is at least one of the best fastapi courses if not the best, but I whish there was a pytest and docker+postgresql deployment sections

By Hardik Gupta on 8/24/2026

Even after having very little experience with backend systems, this course has, along with helping me master FastAPI, taught me so much about the backend fundamantals. Boris' clarity of thought and fluid explainations make the course really very engaging, parctical and helpful!

By Pedro Henrique de Freitas Godinho on 8/13/2026

As explicações dele são muito didáticas e claras. O professor tem domínio sobre o que está ensinando, estou aprendendo muito com o curso.

By Mary P on 8/2/2026

I'm really pleased with this course so far. Boris has a knack for breaking down backend development into its simplest pieces. As someone who has some experience with backend work, I've still learned new vocabulary and the examples he gives have solidified key concepts for me. Excited to progress more through the Rent a Room project!

By Kenneth Gallo on 7/28/2026

This is a great course. Boris gives advanced topics with easy to understand solutions to help me really learn.

By Alexandra Paskhaver on 7/21/2026

Boris is a knowledgable and clear lecturer. As a growing engineer, I appreciate his focus on thinking like a senior and exploring the "why" behind API requests and having consistent data shapes.
